Arroyo, who turns 37 in February, could be looking at a similar framework to the two-year, $23 million deal the Giants gave to right-hander Tim Hudson last week. Of course, Arroyo isn’t coming off a broken ankle, so it would be no surprise if his contract came in a little higher.

Arroyo posted a 3.79 ERA and 124/34 K/BB ratio over 32 starts with the Reds this year and has hurled at least 199 innings in nine straight years. While he’s far from an ace, he would be a welcome addition for a rotation which ranked dead-last in the majors this year with a 5.26 ERA.

Jon Heyman of FanRag Sports reports Thursday that the Orioles “are said to have begun fielding calls of interest” on superstar Manny Machado and “are close to the point of seriously weighing whether to trade him.”

You’d think it would be a no-brainer for the last-place O’s to flip Machado — an impending free agent — for prospects, but Heyman notes there is “still a question whether or not longtime Orioles owner Peter Angelos” will give the go-ahead. One person familiar with the situation put it a “50-50” likelihood. Another suggested that it would take a massive return, which, sure.

Machado entered play Thursday with a sensational .328/.405/.635 batting line, 15 home runs, and an MLB-leading 43 RBI in 49 games. It’d be a real shock if he’s still wearing an O’s uniform by the end of July.

Heyman reported previously that at least nine teams made aggressive plays for Machado this winter, including the Cubs, Phillies, Dodgers, Indians, Diamondbacks, Yankees, Red Sox, White Sox, and Cardinals. A whole lot of those teams still make sense here in late May — maybe all of them except the White Sox.
